Knuckle Clamp

Saw a similar clamp in a catalog picture and thought I could design and print my own version on my 3D printer. The majority of the clamp was printed in one session, the top thumb screw is printed separately, and requires a 1/4-20 threaded insert which can be purchased from Mcmaster. It is meant to be used with T-tracks. To assemble put the two main halves together to form the middle slot and snap into the feet. I haven't actually used one yet but it seems sturdy.
